Foshan lamp FPC circuit board processing

With high wiring density, light weight, thin thickness, good bending characteristics! Combined with hard and soft board (reechas Softandhardcombinationplate) - with birth and development of PCB, FPC plate led to the soft hard couple, this new product. Therefore, the combination of soft and hard board, is the flexible circuit board and hard circuit board, after pressing and other processes, according to the relevant process requirements combined together, formed with FPC characteristics and PCB characteristics of the circuit board. 3, metal base: what kind of metal insulation metal substrate, need to depend on the metal substrate thermal expansion coefficient, thermal conductivity, strength, hardness, weight, surface state and cost conditions such as comprehensive consideration of FPC circuit board headlamp

(2) Observe the electronic components in the circuit have no traces of high temperature, and the electrolytic capacitor has no leakage phenomenon, if so, it should be replaced. 2. Annual maintenance :(1) clean up the dust on the circuit board. (2) on the circuit board of electrolytic capacitor capacity sampling, such as found that the capacity of electrolytic capacitor is less than 20% of the nominal capacity, should be replaced, the life of the general electrolytic capacitor should be replaced for ten years or so, to ensure the performance of the circuit board. In general, considering the cost and technical performance, aluminum plate is the ideal choice. There are 6061,5052,1060 aluminum plates available. Copper plate, stainless steel plate, iron plate and silicon steel plate can also be used if higher thermal conductivity, mechanical properties, electrical properties and other special properties are required. The development trend of PCB manufacturing technology at home and abroad is basically the same, that is, high density, high precision, fine aperture, fine wire, fine spacing FPC circuit board for car lights

3, double-sided flexible plate structure :FPC double-sided flexible plate structure: both sides of the double panel have pads, mainly used for connection with other circuit boards. Although its structure is similar to that of single-layer board, the manufacturing process is very different. Its raw materials are copper foil, protective film + transparent glue. First, drill holes on the protective film according to the location requirements of the pad, and then paste the copper foil. After etching out the pad and lead, paste another protective film with a well drilled hole. , high reliability, multi-layer, high-speed transmission, light weight, thin direction development, in production at the same time to improve productivity, reduce costs, reduce pollution, adapt to the variety, small batch production direction development. The technical development level of printed circuit is generally represented by the line width, aperture, and thickness/aperture ratio on the printed board.

1, the material of the product must be AL1060, must comply with ROHS certification standards, must also be corrosion resistant. 2, the text and screen printing on the aluminum plate plate must be clear, the board must be clean and pollution-free. 3, the size of the thermal conductivity must meet the user's product performance requirements. 4, peeling strength (consistent with CCL IPC test method) 5, in accordance with the provisions of the product name specification version polarity mark and other words screen printing without error, no missing, no reprinting. , it is the circuit schematic diagram into the final form of FPC circuit board, this part of the related design is more difficult than the design of the circuit schematic diagram, we can use ProtelDXP's powerful design function to complete this part of the design.
